In addition, because the watertight locking box 100 is positioned in the inboard space and is hermetically fixed at the operation hole of the gangway plate, the outboard medium is blocked by the watertight locking box 100 and cannot enter the inboard space, so that the watertight locking box can realize bidirectional limiting and watertight locking.
